Hi, I have a problem with optimization. After the purchase, I started playing and the first 5 - 10 minutes of the game is good. But then (or if from the landing point to go very far to one side or deep under the ground) begins to decrease fps. Play becomes difficult and I did not enjoy it. Tell me what to do, maybe I have a weak computer, or you have not optimized the game, but do it in the future?
